Wang Wan,000, was deceitfully surrendered, was recognized by Jiang Wei, and decided to take the plan into account. A few days later, Fu You's men caught a traitor and sent him to Jiang Wei Dazhai.
Carrying a letter from Wang Wan, the traitor agreed to send the grain and grass from Chuankou to the Wei camp on August 20, and asked Deng Ai to send troops to meet him in the Tan Valley. Jiang Wei smiled and said, "Our army is most afraid that grain and grass will not be able to help, this plan is so fierce!" ”
Jiang Wei called Fu You, gave him a plan, and then taught the people to write the same letter, only changing August 20 to August 15. Pick a fine soldier, change into Wei Jun's dress, and send the letter to the Wei camp.
Deng Ai was waiting for wang ou's news with his eyes, when he received the secret letter, he read it repeatedly, and his heart was overjoyed. Immediately wrote a letter back and handed it back to someone to bring back.
Deng Ai dispatched troops to select generals, sharpened his knives and guns, and waited until August 15, so he personally brought 50,000 elite soldiers to the Tan Valley. In the distance, I saw countless grain trucks, one after another, walking in the mountain hollow. Looking closely, the people carrying the grain were indeed Wei Bing.
The general said, "It's already dark, so hurry up and take General Wang out of the valley!" Deng Ai pointed to the front and said, "Looking at the mountain terrain over there, if you ambush a soldier, it will be easy to enter the valley and it is difficult to retreat, or it is better to wait here." ”
